 *(this beta version will eventually become v3.0. We're happy to reach a new major milestone soon, which will be all about the new One Health support! Install this beta using [the instructions here](https://msberends.github.io/AMR/#latest-development-version).)*

   * It is now possible to use column names for argument `ab`, `mo`, and `uti`: `as.sir(..., ab = "column1", mo = "column2", uti = "column3")`. This greatly improves the flexibility for users.
   * Users can now set their own criteria (using regular expressions) as to what should be considered S, I, R, SDD, and NI.
   * To get quantitative values, `as.double()` on a `sir` object will return 1 for S, 2 for SDD/I, and 3 for R (NI will become `NA`). Other functions using `sir` classes (e.g., `summary()`) are updated to reflect the change to contain NI and SDD.
+  * Combined MIC values (e.g., from CLSI) are now supported
   * The argument `conserve_capped_values` in `as.sir()` has been replaced with `capped_mic_handling`, which allows greater flexibility in handling capped MIC values (`<`, `<=`, `>`, `>=`). The four available options (`"standard"`, `"strict"`, `"relaxed"`, `"inverse"`) provide full control over whether these values should be interpreted conservatively or ignored. Using `conserve_capped_values` is now deprecated and returns a warning.
 * `antibiogram()` function
   * Argument `antibiotics` has been renamed to `antimicrobials`. Using `antibiotics` will still work, but now returns a warning.
